left of the brake booster (#2) and unter the part #1 there is a cavity with several hoses. This evening I poked a vacuum cleaner tube in to suck out the dirt and leaves accumulating there. The vac tube must have touched a hose and some kind of oily liquid leaked out.
In order to check the leak I tried to remove the part #1 ( a plastic cover spreading from the wiper motor housing to the right fender), by removing a screw (#7) and lifting the clips 4, 5 and 6 but without success.
My questions:
1) what are the hoses there, transporting what liquid?
2) how can part #1 be removed (I already broke clip #6 )?
I'd appreciate your help, don't want to drive tomorrow to work with this leak.
Thanks!
My car is a 1996 E320 as in my profile.

after being able to remove part #1 I could see the full extent of my predicament.
The small tube B connecting die hoses A and C thru the firewall is broken . Worse it seems B is only a affluent part sharing with another hose at the broken place. I am trying to access the broken location but the plastic undercover beneath D is in the way.
Questions:
1) What is part D, another coolant pump? (Edit: D is the motor for windshield wiper)
2) If I cannot provisorily mend the damage tonight (it will be a long night) can I stuff both ends of A and C and drive to dealership for repair?
Please help!

Omg man, you have yourself a problem. Im not 100% positive but I think its a coolant line for the heater. Find a way to block it for the drive to your local mechanic in the morning. And dont use the heater. Good Luck
Oh and to answer your last question. Yes, stuff them or block them however until you get it to the mechanic in the morning. Its probably not that serious..... Unless you take it to the Dealer!
There is noway I can access the broken place behind the firewall at the location X, the plastic part under the wiper motor is one piece completely extends from fender to fender (from A to B in the picture); besides at the each far end there is a rivet R (not a screw) holding it down.
In the schematic below the break is between B1 and B2 and is at the firewall windshield side, while E is the other hose.
The part I need would be D, B (one part, some kind of Y connector), but the problem is how to access it.

How the hell did you jam the vacuum down there that hard anyway!
It might not be a part that is easily replaced considering its something thats not often broken, but maybe from under the car there is a better perspective. Take it to a guy that knows Mercedes, thats the most important part I think. Some guys pretend to know so you'll trust them into leaving the car so they can foot you the big bill at the end. It pays to know what your talking about if you know what I mean.......
Dont turn the climate control on at all. that wont stop the circulation of coolant from the lines, but It cant hurt. I wouldn't start bypassing any of the lines unless you can make a good connection. Just cap them off and drive to the mechanic.
Part identified: It is the "pipe line" #23, the connector to #107 is broken. I blocked #5, that means no water for windshield washer. The part may be $10,- but it is inaccessible to me, unless I can remove many other parts like the brake booster or the panel under the wiper.
I am still not able to get to dealer for part. Had to go to the office first, will try to get out at lunch time.
At the moment the makeshift fix is:
1) hose #5 is pluggged with slight leak of vaporized coolant, I will loosen overflow reservoir cap to decrease pressure.
2) hose #14 and #107 are open.
The issue of accessing #23 remains unsolved unless either the big plastic panel or the brake booster is removed, of which the latter is more doable since the panel is riveted at both ends.
Any idea on how to remove the brake booster?
Thanks!

Probably easier and better to just drill the rivet out.
